Be it known that doser-'ii Tour, a citizen of. the United o residing atLeavciiworth. in the county l'aeavenworth and State N' Kansas, haveinvented certain new' improvements in y@irain-Car A do declare thefollowing to a l'uli, clear,and e; iet description of the invention.,such as will enable others .skilled in the 'to which it apport-eins tomete and use the l inven4 on which relates to improveinents in Y n cardoors has for its object to improve upon Ythe general construction oi?devi this class to snch extent as to provik compat tively simple yethighly eiiicieat door which may be easily operated.

l'lfith t in n certain nove in unirme coi ier tally e matter beng sup .ipleniented by 'the o pany/ing drawings whic constit ite part of thisapplication and which;

.Figure l. is an elevation of the inner face o one o; iireroyed thesides ot a grain car with the f. isedg For. 2, is a similar rfi 1s.

To this end, S refers 'to one of the upright sides of a commontype of grain carLsaid side having; at its upper edge the usuallongitudinally disposed beam B and being equipped with type of dooriframe l?. of this class, the beam B is disposed on the interior thereofand serves as anchoring means for the sheathing of .the car.

Secured to the inner side of 'the beam B by any preferred means, is apair of vertically spaced horizontal tracks l, said tracks being spacedinwardly from the beam by washers or the like 2. The tracks l receive'therebetween a pair of grooved rollers 3 rotatably mounted on bolts orthe like projecting rearwardly from an elongated horizontally disposedcarriage plate 4, the flat sides of said pate being` positioned inupright planes. Riveted or otherwise secured to the upper corners of theplate i, is a pair of angular brackets or straps through W iose lowerends bolts 6 are passed horizontally, said bolts being' also passedthrough 'the ends oit horizontal shaft 7 spaced inwardly from the plate4i..

Mounted rotatably on the opposite ends of the shaft 7 and havinginwardly extending hubs S received snugly in the opposite ends of aytube 9 which surrounds said shaft, isa pair of peripherally grooveddrums 10,tho hubs of said drums being providerlwith eyes l confinedWithin the tube 9 and receiving the outer hooked ends of a pair of coilsprings i2 also conlined in said tube and encircling the shaft.Theinnerends of the springs 12 are hooked into eyes 13 on a pair ofcollars ift which are slidably keyed on the aforesaid shaft. Thus, whenthe drums l0 are rotated, the two springs l2 will be placed undertension, this'being expedient for reasons to be hereinafter specified.

Partially Wound on the drums and depending therefrom. is a pair ofcables 16 parts throughout the several views and reference will beherein made to the numerous any preferred*y As is usual with carselements by their ybeing in the form of a sheet metal plate whoseopposite ends are received slidably in upright angle-iron guides 19 whenthe door is closed, said guides being secured to the lower end of theframe F as shown. Hinged at its lower edge to the upper edge of thesection 18 by any preferred style of hinges 20, is an upper door section2,1" also in the form of a sheet metal plate, fthe section 2l. beingpreferably of less lengtli'than the section 13.

The upper corners of the Bloor section 21 are provided withlaterallyiextending per-l forated ears 22 of appropriate formationcontacting with other perforated ears 23 which extend laterally from'the sides of the frame F, bolts 24 being passed removably through theperforations in the ears 22 and 23 to hold the aforesaid section 21against outward movement when' the door i's closed. However, when it isdesired to open the door, the bolts 24 are removed, thereby allowing thesection 21 to fold inwardly and downwardly on the section 18. Thetension of the springs l2will now cause the cable 16 to be wound on thedrums 10 as the door is raised. For holding the door in raised position,the two latches 25 are provided,

said latches being shown in the form of uprightflevers fulcrumed betweentheir ends on th" bolts 6 and having said ends offset laterally, thelower ends of said levers being formed with hooks 26 adapted to engagenotches 27 inthe upright edges of the section 18, near the upper end ofsaid edges. In order to effectivelyguidathe section 18 and thus insurethat the lwoks 26 properly engage the notches 27 ahdremain inengagemeni-l therewith as required, the levers 25 are provided withpairs 'of depending guide fingers 28 designed to receive the uppercorners of the section ltherebetween and thus produce 'the resultsdesired.

The upper ends of the levers 25 are pivoted to the outer ends of a pairof longitudinally disposed links 29 which are slidable through tubes 30against the tension of springs 31 confined in said'tubes, the inner endsof the links 29 being provided with eyes to which a pair 'QLcables 32are secured, said cables being extended from the eyes toward the centerof the carriage .plate l and being here passed'over sheaves 33 andconnected by a ring or the like 34. Thus, when a downward pull isexerted on said ring, the latching levers 25 will be so rocked as torelease the door to allow the latter to be lowered.

The carriage plate 4 is normally held in the position shown in Fig. 1 bya horizonramasse Preferably used in conjunction with the parts abovedescribed, is some type of guide for receiving the lower edge of thedoor when opened, this guide being indicated in the present embodimentof the invention in the form of an angle metal bar 36.

A device 0i.l the class specified constructed as above described, willbe found to possess a number of advantageous characteristics and to behighlyA eilicient in operation.

All parts are preferably manufactured as illustrated in the drawings,but yif found :v

expedient, numerous changes may be made within the scope of theinvention as claimed..

l claim 1. The combination with the upright side of a grain car havingthereina door frame, of a horizontal track at the upper end of saidframe and extending laterally therefrom, a carriage mounted on saidtrack and of a length a proximately equal to thel width of the rame,upright guides at the lower ends of the opposed sides of' the frame, adoor mounted in said guides or vertical movement therefrom, windingmeans on the carriage, cables depending from said means and connected tothe door, whereby the latter may be raised from its guides and ahorizontal guide beneath the of a horizontal track at the upper end o'said frame and extending laterally therefrom, a carriage mounted on saidtrack ,and of a length substantially equal to the width of the frame,upright guides extending along the lower ends of the opposed-sides ofthe frame, a lower door section mounted in said guides for verticalmovement therefrom, an upper door section hinged at its lower vedge tothe upper edge of saidlower section and adapted to fold, downwardlythereon, means for normally holding said upper section in uprightposition, winding means on the carriage, cables depending from saidwinding means and connectedto the lower door section whereby the entiredoor may be raised when the upper section is released and folded uponthe lower, and
